Hi all,

I'd like to know how to calculate the values of lqi in metadata header of CC2420 in tinyos 2.0. Is it relevant to the value of rssi? I got some values listed as follows from experiments:
rssi   3A  3E  3F  40
lqi    DF  D9  D7  CE

The LQI values are generated by the CC2420 hardware. Take a look back in the archives; I think there's a discussion of how the hardware calculates it.
